It’s getting there…
The reason I decided to switch to cone 10 reduction vs cone 6 oxidation was to limit the amount of materials I have to buy (and ship) and to reduce the amount of physical labor …

Firing Cone 6 Glazes to Cone 10
The day before yesterday, I did a test run of my cone 6 glazes at cone 10. The firing went a bit cool at 9.5 but close enough. However, I could not find my underglaze …
First Firing of the TDI Conversion Down Draft
Pretty pleased with the results. This is 100% Moon Clay (dug in Moon, Oklahoma), except for the one pot that slumped. That clay was from beside my house. The Moon clay has 8.2% absorption at …
Sandstone Clay Cone 10 Oxidation
This test was done Feb 2022, and I never created a blog post. Almost cone 10 in oxidation. 100% local clay. This clay froze and was a bit stiffer than I’d like. Previous workability tests …
Moon Clay Oxidation Test Cone 10
This is the Moon Clay (Moon, Oklahoma) fired to cone 10 oxidation and cone 10 reduction (the bar). Absorption (3 hr boil 21 hr soak) is 8.2%. It’s an interesting clay to work with. It’s …
Another High Fire Test
EDIT: Fired porosity tested as 2.8%. That’s about perfect as I can fire a bit hotter, and it gives me a bit of wiggle room for reduction. Just out of the kiln this morning. Cone …
Last Cone 5/6 Test
These maybe the last cone 5/6 tests that I do. I won’t say I’ll never return to cone 5/6 because who knows what the future holds. These were fired to cone 5. This is my …
First High Fire Test of a Local Clay
This is the start of a journey, to fire hotter, in the hopes of not having to buy/ship as many ingredients. I’m also hoping to do less mixing and testing, thus, giving myself more time …
Porosity tests of 100% local clay
Tests of my red clay and Moon clay (Moon community, southeast Oklahoma) both of which were just rough processed through window screen. The sandstone revision 3 is the SS3 bar. It’s fine processed with some …
Practical Drying Tests
A couple of largish greenware (unfired) test pots from 100% wild clay. Both of these were dried inside with the AC, but uncovered to see how they would do. They didn’t crack. The red bowl …
